Establishment of a basis for administrative use of PestSurf

Table 8.10. Part of the result sheet generated by the Pestsurf Excel sheet for the downstream part of the sandy loam catchment. The lowest detection value is 300 ng/l, toxicity to fish, daphnies and algae are set to 1000, 5000 and 10000 ng/, respectively. The recorded peaks are shown in Figure 8.24.
Tabel 8.10. Uddrag af resultatpresentationen genereret af PestSurf-Excel-arket for den nedstrøms del af morænelersoplandet. Detektionsgrænsen for tabelgenerering er sat til 300 ng/l. Toxicitetsværdierne for fisk, dafnier og alger er henholdsvis 1000, 5000 og 10000 ng/l. Hændelserne er vist i Figur 8.24.
